i F DBAFT-BIGGINGL YOKE.

eas es? Be it knowirthat I, Atr um COPODlY, a

citizen the frustiii-H'lingarian Empire, residing at Chicagqin'thecounty of Cook and state of Illinois, have invented a certainnewanduseful Improvement in Draftfull, clear, concise, and-e actdescription, reference be ng had to thefaccompanying drawings, forming apart 'of this specifica- "'tion. This *iventloirrelates to nnprovementsin An object of theinvention is to provide a yoke for draft riggings ofrailway cars WlllCll may be readlly attached to and de-' l tached from astandard draw bar and which,

of a yoke embodying my improvements and 3 showing the same attached to adraw bar 30 devices,

when in operative position, is prevented by integral means thereonfromseparating laterally from the draw bar.

The invention furthermore consists in the improvements inthe parts anddevices and in the novel combinations of the partsland as herein shown,described or claimed.

In the drawlng forming apart of this specification, Figure 1 1s a topplan view and indicating in dotted lines the position of the usual stopcastings. Fig. 2 s a side elevation of thefstructure illustrated in Fig.

1. Fig. 3 is a vertical sectional view taken.

on the line 33 of Fig. 2 and Fig. {1 is a horizontal sectional viewtaken substantially on the line 4-4 of Fig. 2.

In said drawing, 10 denotes a draw bar of M. C. B. specifications, thesame having 1 upper and lowerlshoulders 11-l1 and cou- 4 pler key slot12. My improved yoke is designated generally by the reference A and,

l as shown, comprises" two like members,

i which are in the form of links or arms 13-43, each link or arm 13being provlded at its rear end with a shoulder 14 adapted to engage therear side of a rear follower,

said shoulders 1 being braced by a horizontal web or flange 15. At itsfront end, each arm 13 is provided with a pair of spaced flangesengagingthe upper and lower surend with a shoulder 17 adapted tocooperate bar. Each pair of flanges 16-16 is connected by a verticalweb, whichhas a curved mS pecificati on of Letters Patent.

inwardly extending portion 18 andan out wardly curved portion 19 (seeFig1-). In-

termediate each pair of flanges 16 16 and preferably integral with theweb 18-19, is an inwardly extended projection or lug 20, which isadapted to enter the elongated key slot :12, said lug or projection 20,at its forward end is provided with an overhang or finger 21,which whentheyoke arms are in the position clearly indicated in Fig. 4c, overlapsthe wall 22 surrounding the'key slot 12, there being sufficientclearance between the wall22 and the adjacent edge 23 of the. lug

to permit the latter to be moved forwardly in the slot when theparts arebeing draw barby inserting the lugs 202O with in the key slots 12 andwhile the yoke arms draw bar. The yoke arms are then swung 13 13 are atan angleto the line of the' inwardly toward each other to bring theshoulders 17'17 thereon in engagement with the shoulders 1l11 and whenthe yoke arms have been brought into parallel engagement with the drawbar, the overhang or finger 21 will engage the walls 22 surrounding thekey slots and thus prevent the yoke arms from separating laterally fromthe draw bar. As will be understood, the lugs 20-20 are not required toundergo any severe strain, inasmuch as under draft, the forces aretransmitted from the draw bar to the arms 1313 through the shoulders 17and flanges 16 and under bufl' the forces are transmitted directlythrough the draw.

bar to the front follower (not shown.) In the structure which I haveshown, no connection is provided between thevrear ends of the yoke arms13- 13 and the same will be held in proper position by means of the gearproper and the stop castings in which the yoke arms work. Thearrangement is very simple and provides an easy means of attachment tothe draw bar and without the necessity of keys or the usual rivets.

1. A yoke for railway draft riggings which comprises two members, eachhaving an inwardly extended lug at the front end thereof adapted toengage in a coupler key slot of a draw bar, each of said lugs having alongitudinally extended inner end adapted to engage a wall of said keyslot to prevent lateral separation of the yoke members from the drawbar.

2. Ina yoke for railway draft riggings,

two horizontally arranged arins, each of which is provided at its frontend; with an inwardly extending lug arranged to enter the coupler keyslot of a draw bar, eachof said lugs having integral means adapted toov'eilap the'edge of the wall forniing saidkey slot and thus preventinglateral sepa-' ration of the yoke arms from the draw bar.

A yoke of tliecharacter described, comprising twoarnis each of? which-isprovided at its'fo'rward end with upper and lower shoulders arranged toengage the usual shoulders on "a draw bar, each of said nernhers beingfurther provided with an inwardly r extending lug arranged to enter thecoupler 'key slot of a draw bar, the lug having an overhang to engagethe edge of the wall surrounding the key slot. p
